With a militant drumbeat and an ominous tone, a campaign ad here warns that election of Conservative Party leader Stephen Harper "would bring a smile to George W. Bush's face."

Well behind in the polls heading into a parliamentary election, the governing Liberal Party led by Prime Minister Paul Martin brought what in Canadian politics is a most damning indictment: Martin's opponent is too close to the Americans, the party's ads say.

"Mr. Harper, the United States is our neighbor, not our nation," warns one.

Harper is "pro-Iraqi war, anti-Kyoto, socially conservative ... Bush's new best friend," says another ad Yet another ad speculates that Harper may have received illegal campaign funds from American conservatives. The ads are running before an election in which Martin's party appears likely to lose its hold on the government. After Christmas, the Conservatives, the main opposition, jumped suddenly from behind and lead the Liberals by 10 percentage points, 38 percent to 28 percent, according to a poll for the Globe and Mail newspaper.
